Parts for your 2006 Nissan Primera-Thrust bearing

2006 Nissan Primera thrust-bearing: what it is and when to sort it

Technical references including the Nissan Primera P12 Series Service Manual (CL – Clutch, EM – Engine Mechanical) and typical parts catalogues for the P12 show that 2006 manual-transmission models use a clutch release (thrust) bearing, integrated with a hydraulic concentric slave cylinder inside the bellhousing. The engine across all 2006 Primera variants also uses crankshaft thrust bearings to control end float. CVT-equipped cars don’t have a clutch release thrust bearing, which aligns with JATCO CVT service literature that doesn’t list a conventional clutch release system.

On a manual 2006 Primera, the clutch thrust bearing’s job is simple but vital: when the driver presses the clutch, the hydraulic system pushes the bearing against the pressure plate’s diaphragm spring, cleanly separating engine and gearbox. In the P12, this bearing is typically part of a combined concentric slave cylinder (CSC), so it’s serviced as a unit. Because it lives inside the gearbox bellhousing, replacement involves removing the transmission, which is why most workshops swap the CSC/thrust bearing whenever a clutch kit is fitted.

As part of regular servicing, it’s smart to refresh the clutch hydraulic fluid (shared with the brake fluid on many cars) every two years with the correct DOT spec, check for pedal feel changes, and look for any signs of hydraulic leaks. Telltale noises when the pedal is pressed—squeal, rumble or a gritty feel—point to a worn thrust bearing. The owner will also want to avoid “riding” the clutch at lights, as that keeps the bearing loaded and shortens its life.

When tackling a clutch job on a 2006 Primera manual, best practice is to:

• Confirm the transmission type: manual models have the CSC/thrust bearing, CVT models don’t.
• Replace the CSC/thrust bearing with the clutch kit and inspect the flywheel surface.
• Follow the P12 torque specs and bleeding procedure from the Nissan service manual.

Crankshaft thrust bearings in the engine are not routine service items and are typically only inspected if there’s suspected end-float or during an overhaul—again covered in the EM section of the factory manual.

Popular questions

Does every 2006 Nissan Primera have a thrust bearing?
Every engine has crankshaft thrust bearings. A clutch thrust bearing is fitted only on manual-transmission models, CVT versions don’t use one. This setup is described in the P12 Service Manual’s CL and EM sections and reflected in parts catalogues listing a CSC/release bearing for manuals only.

What are the signs the clutch thrust bearing is failing?
Noise or roughness only when the clutch pedal is pressed, a pulsing pedal, difficulty selecting gears at a standstill, or fluid leaks from the bellhousing area. If the noise disappears when the pedal is released, that’s classic thrust-bearing territory. Driving can worsen damage, so it’s best to book it in promptly.

How much does replacement usually cost in Australia or New Zealand?
As a guide, a CSC/release bearing is often replaced with a full clutch kit. Parts typically land around AUD/NZD $450–$1,200 for quality kits (including the CSC), plus 5–8 hours’ labour depending on engine/gearbox combo. Total fitted price commonly ranges from about AUD/NZD $900–$2,000, with extra if the flywheel needs machining or replacement.
